This invention relates tonovel details. of

construction of annular devices such as covers Figs. 4 and 5 are enlarged detailed sectional views;

Figs-6 and 7 are detailed sectional views of other constructions. r

The device The device shown in Figs. 1-5 of the drawing, which may well be used as a cover for an nular objects such as coils of wire, tires, etc. includes a planar side wall 10, which may be annular or circular and which has a circular or substantially circular outer edge, and also a cylindrical top wall 12, connected and secured to the side wall. As shown, the elements of the cylinder of the top wall are perpendicular to the planar side wall.

The side wall is provided with an inwardly turned flange portion 14 which lies adjacent a retroverted portion 16 projecting inwardly from the folded over edge 17 of the top wall.

In this edge is disposed a bead forming annular member 18. In the device of Figs. 8 and 4 the member 18 is of rope, or the like, and is not form sustaining, that is to say it does not of itself retain its annular shape. In the device of Fig. 5 the member 18 is of Wire or the like and is form sustaining, retaining its annular shape without assistance.

When a rope or the like comprises the member 18, as in the device of Figs. 3 and 4, the

' annular corner may be, and in some constructions preferably is, provided with an annular wire ring 20 disposed between the portions 14 and 16 of the cover, and having an inherent tendency to expand and tension the walls 10 and 12.

If desired,-where the device has two side walls, a ring 20 may be provided for both annular corners, or may be provided forone onlyof the annular corners, preferably for the annular corner which ismost often presented to view.

Lines of stitching 21 are provided to se oure the aforementioned parts in juxtaposition, as indicated.

7 For stiffening, ornamenting, reinforcing, binding, etc., the edge or corner of the: device, a C cross section. molding 22' maybe applied to the beaded edge 17, as shown. The molding preferably encompasses the bead of edge 1?! in such a mannerthat it projects forwardly from the top wall, rather than, as might be expected, radiallyioutwardly.. This is clearly brought out in Fig. 4.. V. Where the member 18. is not form sustain.-

' ing, the molding 22 should be of. fairly heavy 7-0 cross section, since. it must have suflicient rigidity to enable itto retain its: annular shape without assistance from the member 18. Where the member 18 is; of wire. or: the like, the molding may be relatively light. in cross section, and 'may' be considered as lit tlemore than aplating. I V

- Further, in some cases,"as in. Fig. 4,.thei molding may' be applied to the beaded edge 17' in such; a manner that, though non re- 8'0 movable from theedge, i-t-is loose thereona. This. feature permits relative circumferene tial movement between the molding, and-the edge l'? and prevents puckering etc. of the material near the edge. Y

' In other cases, as in Fig. 5, the molding may be clinched onto the bead tightly, in a. manner to prevent relative. movement be tween the molding and the edge.

Still further, the molding is applied'to the cover in such a mannerthat, though icon tracted to the diameter of the rope 18 to which it is applied, it possesses an inherent tendency to expand to a greater diameter: This prevents the tendency of the molding, when applied, to wave itself out of a true plane. g V l Still further, the moldingmay be p'olished, plated orcoated, as desired, though", for purposes of-economy, it is preferred to polish or plate only the forward part or wall of the molding, leaving unpolished those portions thereof behind the beaded edge of the device.

Still further, while the device is shown in use as a cover for a tire '1, it is clearly understood that the device may be used as a cover for other annular or substantially annular objects. For example the device may be used as a cover for wire coils: Other uses might also be suggested. p

In Fig. 6, there is shown a cover or the like wherein the top wall 40 has a central bead 41 provided with a molding 42, projecting radially outwardly, and wherein the illner annularedge of the side wall 43 has a radially inwardly projecting bead 44 on which is a radially inwardly disposed molds ing 45. 1

' In Fig. 7 there is shown a corner construction, between top wall 48 and side wall 49 whereinbe'ad50 projects radially outwardly and is coveredby a molding 51. I

This application is a division of my co pending application Serial Number 616,137, filedJune 8, 1932.. r 3

Now having described my invention, and embodiments thereof, it will be observed that the same is not to be limited to the specific details shown, but only by the scope ofthe claims which follow.

What I claim is;

1. In an annular corner'construction for annular objects'of pliable material, the combination of a planar side wall, a cylindrical top wall, anannular bead adjacent the annular corner of said walls and firmly anchored with respect to said walls, and an annular C cross section molding externally encompassing and supported on said bead by having its edges turned in over said bead, the molding being looseenough with respect to the head, as not to bind thereon and thereby cause puckering of pliable wall parts to which said beadis anchored, the molding also being loose enough thereon so as to permit relative circumferential movement between the molding and the bead.

2; In combination, pliable annular wall parts, means forming an annular bead anchored with respect thereto, and an annular, C cross section, molding externally encompassing said bead and supported thereon by having its edges turned in thereover, the molding being loose enough with respect to the bead, as not to bind thereon and thereby causepuckering of pliable wall parts to which said head is anchored, the molding also being loose enough thereon so as to permit relative circumferential movement between the molding and the bead.

3. In combination, pliable annular wall parts,-means forming an annular bead anghored with respect thereto,'andan annular,

cross section,lmolding externally encome.

ing an 'inherenttendency to expand to a greater diameter.

.4. In an annular corner construction for annular objects of pliable material, the combination of a planar side wall, a cylindrical top wall, an annularbead adjacentthe annular corner of said walls and firmly anchored with respect to said walls, and an annular C cross section molding externally encompassing and supported on said bead by having its edges turned in over said bead, the molding being loose enough with respect to the bead, as not to bind thereon and thereby cause puckering'of pliable wall parts to 7 which said bead is anchored, themolding also being loose enough thereon so as to permit relative circumferential movement between the molding and the bead, the molding, though contracted to, the diameter of the bead, having an inherent tendency to expand to a greater diameter. 7 In testimony whereof I aflix my signature.
